Referring mptliegdrawlings 1+ l designates a portion of the body of a shuttle which in general respects is of usual construction. 2 designates a spindle which carries the bobbin 3, said spindle having its inner end connected with the head 4 which is mounted in the body 1 by the pivot pin 5 as the axis of saidv head andV consequently of said spindle.

The lip 21 has its outer end rounded and seatedy knnekle .te 'said head. Ofn this basl circled by the spring 24 which Vbears against said knuckle and is seated on the base of the recess 25 in the interior of the nose portion of the body of the shuttle, the pressure of It' Willems be ses? -tlisttlis llvbie .is held in an operative position on the spindle ands Theseflfnsrton 0f Athe @steh-12s formedwith an elbow. 16. toward? Ofwlrch -s the said spring on the knuckle retaining the latter in engagement with the head 4 while permitting said knuckle to rock on said head in the movements of the spindle 2. V

Theportion of the head 4 belovi7 the yknuckle is formed with the depending limb 26 which is adapted to abut the adjacent wall of the body l as a stop 30 to limit the closing of the spindle and holds the head irmly in position during the operation of the shuttle.

It will be seen that when the spindle is closed or in operative position the bobbin will be engaged by the catches at different places and so doubly locked on the spindle whereby the bobbin cannot be withdrawn from the latter, the head 4 now being controlled by said knuckle and rendered immovable in the locked positions of the catches on the bobbin as will be apparent on reference to Figure 2.

lVhen the bobbin is to be removed the spindle is thrown up as in Figure 4. Then the head 4 turns on its axis with the spindle whereby the knuckle 19 ulcrumed on the said head by the lip 2l is turned downwardly and the catch 6 carried by said head is raised whereby its heel end is in the path of the upper lip 20 of the knuckle which lip is moved forwardly by the knuckle and so said end enters the recess 22 of the latter and it is pressed downwardly by said lip 20. This raises the end of the catch that has the tongue 8 thereon, see Figure 4, and so said tongue is removed from the groove 9 of the bobbin and the bobbin is no longer held by said catch. Simultaneously therewith the lower Catch 12 is carried up by the head 4 whereby the elbow 16 is advanced to the pin 17 and then rides upon the latter when the terminal limb 18 being offset from the main length of the catch is placed also on said pin and rides thereon so as to press said limb 18 towards the head 4 and as aconsequence defiectthe end of the catch 12 that has thereon the lip 14 from the bobbin and so said lip is removed from the bobbin, thus unlocking the latter. The head 4 is now controlled by said knuckle in the unlocked position of said catches, as apparent in Figure 4, and the catches are retained in said unlocked position.

As both catches are now disconnected from the groove in the bobbin the latter is unlocked and so may be' slipped from the spindle and consequently entirely removed there- This will be apparent in Figure 4, the bobbin, however, having been removed therefrom. Gn replacing a bobbin and throwing down the spindle the catches are released of the knuckles and deiiecting pin respectively and restored to the normal positions when both catches are interlocked with the bobbin in normal position as before stated and shown in Figure 2.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is l. In a shuttle, a bobbin holding spindle, a pivotal head with which said spindle is connected, a plurality of catches mounted on said head adapted to engage the bobbin at different places thereon to retain it in operative position, and a knuckle adjacent to the head adapted to be ulcrumed thereon and adapted to engage one of said catches to remove the latter from the bobbin, and an abutment member in the shuttle adapted to engage the other catch to release the bobbin 3nd permit it to be removed from the spin- 2. In a shuttle, a bobbin holding spindle, a pivotal head with which said spindle is connected, a catch mounted on said head adapted to engage the bobbin and retain it in operative position, a rocking knuckle operatively arranged with respect to said head, and an abutment member in the shuttle, said catch having therein an elbow which is adapted to ride on said member when the spindle is raised and thereby remove said catch from the bobbin and release the bobbin whereby it may be removed from the spindle said head being adapted to cooperate with said knuckle to retain said catch in its unlocked position.

3. In a shuttle, a bobbin holding` spindle, a pivotal head with which said spindle is connected, a plurality oi' catches mounted on said head adapted to engage the bobbin, an abutment member in the body, one of said catches having thereon an elbow which is adapted to ride on said member when the spindle is raised, said catch having a depending limb which is adapted to engage said abutment to open said catch, a rocking knuckle operatively arranged with respect to said head whereby said head is controlled in the locked and unlocked positions of said plurality of catches, the body having therein a stop with which said limb is adapted to abut serving to limit the motion of said head in the closed positions o1" the catches.
